To all whom it may concern: I

'Be it known that I, HEINRICH OTTO. ADAM, chief engineer, a subject of the German Einperor,=.residing in the city of Dresden, Kingdom of Saxony, German Empire, have invented a certain new and useful Device for Taking in Coal at Sea, of which the following is a specification. a 1 Y I The taking in of coal from the coal-ship, or, generally speaking, from one ship onto the other ship, as heretofore practiced, as is well known, used to take place by connecting ing-rope by means of iron hooks of special" construction, which when they arrive upon the ship to be loaded abut against a stop, which acts upon the said hooks in such a manner as to detach them from the hoistingrope, so that the hooks with the coal-bags drop off from the rope. This manner of hoisting the coal from one ship to the other presents, however, a number of inconveniences, among which in the first place the fact has to be mentioned that the detaching of the hook sometimes fails to work. This drawback is also coupled with the inconvenience that on account of the ver often greatly changing and varying elevation of the'hoisting-sheave the hooks with the coal-bags are not carried along with sufficient security, the

hooks getting pushed close to each other and failing to be detached in time from the rope. Whenever any stop or irregularity has, however, occurred in the regularity of the hoisting operation, the locating and removing of the difficulty cause in most cases a loss of sometimes very valuable time.

To dispense with these difficulties is the object of the present invention, and this is accomplished by using ordinary hooks in place ofthe hoisting-hooks heretofore employed, which are rather expensive and present the above-mentioned inconveniences, the said ordinary hooks being, however, not directly fastened to the hoisting-rope, but by means of tow-loops, the tow being severed by mechanical means as soon as thecoal-bag has arrived at the ship it is desired to load at a suitable place.

The new arrangement for taking in coal at Specification of Letters Pateht.

' Iaterited. Jan.'1,1 907 sea is shown diagrammatic ally Figure l o f the accompanying drawings,.while Figs. 2 to L. illustrate the operation of slinging the rope,

and Fig. 5 is a device for the lifting off of the severed hitch of tow in case the hitch is not drawn off from the hoisting-rope by -the' dropping coal-bag. T

- The coal-ship a is connected by. the hauling rope or-hawser c to the ship bwhere the coal is to be taken in. Then the endless-rope cir. cuit is laid in the ordinary manner, thecoal-, bags being suspendedfrom the'up'penbranch c of said circuit. 1 The hitch of .tow is slung around: the running hoistingerope in the manner illustrated in Fig. 13 \of the drawings that is to say, whilethe-one closed end of thehitch of tow d is suspended at one side. i of the hoisting-rope the other closed end is passed through the depending. loop-forming end and it is. thenpassed around the-hoist? ing-rope in such a manner that the two closed ends will then be suspended fromthe hoisting-rope c, forming a double hitch, in which the coal-bag is suspended by means of an ordinary S-shaped hook. The coal-bag will then tighten the hitch put around the hoisting-rope to such an extent that the hitch is sure to be seized and carried along by the hoisting-rope in its travel. The rope hitch 01 Will thereby pass onto the ship I), where it strikes against a knife 6, which is arranged in any suitable manner near the sheave f, and the hitch of the tow is thereby cut through. As soon as one side of the hitches of the tow has been severed the weight of the suspended coal-bag pulls the entire tow off from the wire rope, inasmuch as the bag is still suspended from the hitch. Hence the bag does not only drop ofi, as required, at a convenient place, but the tow by which it has been carried thus far is also pulled off by mechanical means from the hoisting-rope, so that it is prevented from interfering with the movement of the hoisting-rope and withthe correct transportation of the following coal-bags. In view of the great speed at which the hoisting rope usually runs the slinging around of the tow (1 may be attended with difiiculties and may even cause danger to the operator. This is avoided by passing the hoisting-rope at the place where the loading is to be effected through a stationary hollow cone g, Figs. 1 and 2, of such length that the operator is able to effect the formation of hitch described upon said cone. By this means there is no danger to the operator, and when the bitch is correctly formed the operator merely pushes it by hand "or .by means ofta lever unto the running hoisting rope, and he then suspends the coal-bag from (it, which will then tighten the hitch. Inasmuch as the hitch of tow is now directly suspended with the coal-bag instead of ltheldouble}hitch,-
